Tabletop role-playing game in the context of Non-playing character

A role-playing game (sometimes spelled roleplaying game, or abbreviated as RPG) is a game in which players assume and play out the roles of characters in a fictional setting. Players take responsibility for acting out these roles within a narrative, either through literal acting or through a process of structured decision-making regarding character development. Actions taken within many games succeed or fail according to a formal system of rules and guidelines.

There are several forms of role-playing games. The original form, sometimes called the tabletop role-playing game (TRPG or TTRPG), is conducted through discussion, whereas in live action role-playing (LARP), players physically perform their characters' actions. Both forms can have features of a storytelling game. In both TTRPGs and LARPs, often an arranger called a game master (GM) decides on the game system and setting to be used, while acting as a facilitator or referee. Each of the other players then takes on the role of a single character in the experience.

A player character (also known as a playable character or PC) is a fictional character in a video game or tabletop role-playing game whose actions are controlled by a player rather than the rules of the game. The characters that are not controlled by a player are called non-player characters (NPCs). The actions of non-player characters are typically handled by the game itself in video games, or according to rules followed by a gamemaster refereeing tabletop role-playing games. The player character functions as a fictional, alternate body for the player controlling the character.

Video games typically have one player character for each person playing the game. Some games, such as multiplayer online battle arena, hero shooter, and fighting games, offer a group of player characters for the player to choose from, allowing the player to control one of them at a time. Where more than one player character is available, the characters may have distinctive abilities and differing styles of play.

A storytelling game is a game where multiple players collaborate on telling a story. Some games primarily feature spoken storytelling, while others primarily feature collaborative writing. In some storytelling games, such as many tabletop role-playing games, each player represents one or more characters in the developing story. Others involve more third-person narrative.

A gamemaster (GM; also known as game master, game manager, game moderator, referee, storyteller, or master of ceremonies) is a person who acts as a facilitator, organizer, officiant regarding rules, arbitrator, and moderator for a multiplayer role-playing game. The act performed by a gamemaster is sometimes referred to as "gamemastering" or simply "GM-ing."

The role of a GM in a traditional tabletop role-playing game (TTRPG) is to weave together the other participants' player-characters' (PCs) stories, control the non-player characters (NPCs), describe or create environments in which the PCs can interact, and solve any player disputes. This basic role is the same in almost all traditional TTRPGs, with minor differences specific to differing rule sets. However, in some indie role-playing games, the GM role significantly differs from the traditional pattern. For example, in Powered by the Apocalypse systems, the other players assist the GM in creating both the NPCs and the details of the campaign setting.

Tabletop games or tabletops are games that are normally played on a table or other flat surface, such as board games, card games, dice games, miniature wargames, tabletop role-playing games, or tile-based games.

Role-playing video games, also known as computer role-playing games (CRPG), comprise a broad video game genre generally defined by a detailed story and character advancement (often through increasing characters' levels or other skills). Role-playing games almost always feature combat as a defining feature and traditionally used turn-based combat; however, modern role-playing games commonly feature real-time action combat or even non-violent forms of conflict resolution (with some eschewing combat altogether). Further, many games have incorporated role-playing elements such as character advancement and quests while remaining within other genres.

Role-playing video games have their origins in tabletop role-playing games and use much of the same terminology, settings, and game mechanics. Other major similarities with pen-and-paper games include developed story-telling and narrative elements, player-character development, and elaborately designed fantasy worlds. The electronic medium takes the place of the gamemaster, resolving combat on its own and determining the game's response to different player actions. RPGs have evolved from simple text-based console-window games into visually rich 3D experiences.

A non-player character (NPC) is a character in a game that is not controlled by a player. The term originated in traditional tabletop role-playing games where it applies to characters controlled by the gamemaster (or referee) rather than by another player. In video games, this usually means a computer-controlled character that has a predetermined set of behaviors that potentially will impact gameplay, but will not necessarily be the product of true artificial intelligence.

Dungeons & Dragons (commonly abbreviated as D&D or DnD) is a fantasy tabletop role-playing game (TTRPG) originally created and designed by Gary Gygax and Dave Arneson. The game was first published in 1974 by Tactical Studies Rules (TSR). It has been published by Wizards of the Coast, later a subsidiary of Hasbro, since 1997. The game was derived from miniature wargames, with a variation of the 1971 game Chainmail serving as the initial rule system. D&D's publication is commonly recognized as the beginning of modern role-playing games and the role-playing game industry, which also deeply influenced video games, especially the role-playing video game genre.

D&D departs from traditional wargaming by allowing each player to create their own character to play instead of a military formation. These characters embark upon adventures within a fantasy setting. A Dungeon Master (DM) serves as referee and storyteller for the game, while maintaining the setting in which the adventures occur, and playing the role of the inhabitants of the game world, known as non-player characters (NPCs). The characters form a party and they interact with the setting's inhabitants and each other. Together they solve problems, engage in battles, explore, and gather treasure and knowledge. In the process, player characters earn experience points (XP) to level up, and become increasingly powerful over a series of separate gaming sessions. Players choose a class when they create their character, which gives them special perks and abilities every few levels.

An indie role-playing game is a role-playing game published by individuals or small press publishers, in contrast to games published by large corporations. Indie tabletop role-playing game designers participate in various game distribution networks, development communities, and gaming conventions, both in person and online. Indie game designer committees grant annual awards for excellence.

In the early 2000s, indie role-playing discussion forums such as The Forge developed innovative design patterns and theories. In 2010, the game Apocalypse World established the popular design framework Powered by the Apocalypse, inspiring hundreds of similar games. Starting in the early 2010s, indie game publishing provided new opportunities for LGBTQ writers to share underrepresented stories.

Powered by the Apocalypse (PbtA) is a tabletop role-playing game design framework developed by Meguey and Vincent Baker for the 2010 game Apocalypse World and later adapted for hundreds of other indie role-playing games.

A campaign setting is a setting for a tabletop role-playing game or wargame campaign. Most campaign settings are fictional worlds; however, some are historical or contemporary real-world locations. A campaign is a series of individual adventures, and a campaign setting is the world in which such adventures and campaigns take place. A campaign setting is typically designed for a specific game (such as the Forgotten Realms setting for Dungeons & Dragons) or a specific genre of game (such as historical fantasy or science fiction), though some come from existing media (such as movies, shows, novels, or comic books). There are numerous campaign settings available for purchase both in print and online. In addition, many game masters create their own, which are often called "homebrew" settings.

Examples of major campaign settings include the Dungeons & Dragons campaign settings and the World of Darkness, and licensed settings such as the Star Trek science fiction universe, and the Avatar: The Last Airbender fantasy world.

Paper-and-pencil games or paper-and-pen games (or some variation on those terms) are games that can be played solely with paper and pencils (or other writing implements), usually without erasing. They may be played to pass the time, as icebreakers, or for brain training. In recent times, they have been supplanted by mobile games. Some popular examples of pencil-and-paper games include tic-tac-toe, sprouts, dots and boxes, hangman, MASH, paper soccer, and spellbinder. The term is unrelated to the use in role-playing games to differentiate tabletop games from role-playing video games.

Board games where pieces are never moved or removed from the board once being played, particularly abstract strategy games like Gomoku and Connect Four, can also be played as pencil-and-paper games.

A melee (/ˈmeɪleɪ/ or /ˈmɛleɪ/) is a confused hand-to-hand fight among several people. The English term melee originated circa 1648 from the French word mêlée (French: [mɛle]), derived from the Old French mesler, from which medley and meddle were also derived.

The 1812 tabletop wargame Kriegsspiel, and H.G. Wells' 1913 Little Wars, referred to the hand-combat stage of the game as a melée, or mêlée, respectively. The term was brought over to tabletop role-playing games such as Dungeons & Dragons, and in turn to role-playing video games, to describe any close-combat encounter.
